13.8 The goalkeeper must not be raised from the playing surface prior to a shot at goal.

13.9 Before a shot is taken the goalkeeper must not be tilted more than 45 degrees from the vertical.

*****If a shot at goal is unsuccessful as a result of an infringement of any of these rules, then the attacking side may request 'Back'. If the 'Back' claim is allowed, the ball and figures are returned to their former positions and the shot is retaken. If the 'Back' claim :is rejected, the game continues as normal****

It's one of those rules that you can choose to interpret how you please in a club .. but I've played against people who purposely lay their keeper flat when passing back and that does bloody annoy me ...
